According to Bronsted Lowry concept, the correct order of strength of bases follows the order:

Options

A. `CH_(3)COO^(-) gt Cl^(-) gt OH^(-)`
B. `CH_(3)COO^(-) gt OH^(-) gt Cl^(-)`
C. `OH^(-) gt CH_(3)COO^(-) gt Cl^(-)`
D. `OH^(-) gt Cl^(-) gt CH_(3)COO^(-)`

Answer

C

Explanation

Relative strength of bases can be shown by their conjugated acids.
Conjugate acid of `OH^(-) " is "H_(2)O` which is a weak acid conjugate acid of `CH_(3)COO^(-) " is " CH_(3)COOH` which is stronger than `H_(2)O` .while conjugate acid of `Cl^(-)` is HCl which is strongest out of there. so the order of relative strength of bases is `OH^(-) gt CH_(3)COO^(-) gt Cl^-)`
